provide an efficient means for supportmg the coil spring andat the sametime permitting the use of a cover for enclosing the spring to protectthe same from the action of the which any of the parts may be readilyreplaced in event of breakage. I

These and other objects I attain by the ronstruction shown in theaccompanying drawing, wherein for the purpose ofillustrationis shown apreferred embodiment of my invention and wherein:- 7

' Figure 1 is a longitudinal sectional view taken through a portion of acushion wheel J constructed in accordance with my invention and taken onthe line 11 of Figure 3;

Figure 2 is a side elevation thereof;

Figure 1; v V r v Figure 4: is an enlarged detail 88013101151111 lartothat shown n Flgure 1.

, eferring now more particularly d1."aw1ng,the numeral 10 generallydeslgnates an annularseat provided 111 its outer face "with agroove 11having an arcuate face.

This groove receives theinner face of a circular sprlng helix 12extendmg entlrely spring,if so desired, may be provided with angularextensions 13 engaging n an openingformed in the seat topreventcircumferg ential movement of the spring upon the seat.

An annular wear band 1 4 is provided, this *band fitting'the outersurface of the helix and being transversely curvedto conform to thetransverse curvature of the helix. The "Lends of the band are preferablyinturned and] are secured together by bolts, as at l6. The annularseat/10 hereinbefore referred to 1s c. preferably made in two sections10*, 10",each

'having'a wing 17 projecting beyond the side} face of the sections andextending the seat An important object of the invention is to Figure 3is a section on the line 33 of to the around'the annularseat 10. r Theends of'this I of the'helix and a ca's1ng e11clos1ng the hel1x [toprotect the same fromj the elements, said 7:, 1926.

which is provided for the helix, -The annular member 10 is furtherprovlded with openings 18 paralleling-the axis of the member.

receiving bolts 19 for clamping together upon the body of the seat splitrim'sections 20, These rim sections, in addition to pro;

viding a means for applying the tire to the cover member 22 completelysurrounding the wear plate 14 and .helix12 to protect the rtiazw to fwneel, also'provide' meansfor attaching to the annular member 10 theedges'Ql of a ablematerial ahd'may. be made of anydesired thickness. Itwill be obvious that the coils of the hGllX' will yield under pressure,

thus cushioning. the movement ofithe wheel 7 over the ground and it willalsovbe'obvious that the plate 14 will protect the casing 22 against theaction of the coils. 7

Since the construction hereinbefore set "I claim I V I s A cushion tirecomprising an annular seat,- an annular helix 1 engaged with the outerface ofthe seat and} having engagement with the seat to preventcircumferential ture except. as hereinafter claimed.

while permitting free movement of the coils of the helix intermediatethe ends'thereofpan annular wear plate abutting-the outer face movementof lthe helix bodily upon the seat v forth is obviously capable of acertain range 3 of change and modification without material ly departingfrom the spirit of the invention, f

I do not limitmyself to such specific strucannular seat having its outerface a groove "in two sections each 'providedwith a wing .7
